How do you find a mathematical domain?
The domain of a function is just all the x-values that have a corresponding y-value. Typically, you need to check for discontinuities or vertical asymptotes. For example, any x value that causes the denominator of a fraction to be 0 must be excluded from the domain, since you can't divide by 0. A simple case would be f(x) = 1 / x If x = 0 , the denominator is 0 and the function is undefined; all other values of x have a corresponding value for f(x), so the domain would be x < 0 and x > 0, or (-∞, 0) U (0, ∞). >>M.T.<<
What are the solutions for the quadratic equation x2 plus 6x equals 16?
x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
What is the vertex for the parabola y equals x squared plus 4x plus 5?
The vertex of a parabola is the minimum or maximum value of the parabola. To find the maximum/minimum of a parabola complete the square: x² + 4x + 5 = x² + 4x + 4 - 4 + 5 = (x² + 4x + 4) + (-4 + 5) = (x + 2)² + 1 As (x + 2)² is greater than or equal to 0, the minimum value (vertex) occurs when this is zero, ie (x + 2)² = 0 → x + 2 = 0 → x = -2 As (x + 2)² = 0, the minimum value is 0 + 1 = 1. Thus the vertex of the parabola is at (-2, 1).
Approximation of sin x by x?
the value of sin(x) lies between -1 to +1. the approx value of sin(x)/x = 1 when x tends to 0 & sin(x)/x = 0 when x tends to infinity.
What is the value of x in the equation 32x - 16 equals 512?
If: 32x-16 = 512 Then: x = 16.5
Write 16 to the 3rd power as a product of the same value. Then find the value?
16 x 16 x 16 = 4096
What is the value of x in x plus 16 equals 26?
x+16=26Subtract 16 from both sides and you will find that is equal to 10, x=10 and that's its value.
How do you find the absolute value of something?
If a number is not less than zero then that is its absolute value. If a number is less than zero, its negative is its absolute value. So, if |x| denotes the absolute value of x, then |x| = -x for x<0 [since if x<0 then -x>0] and |x| = x for x>= 0
What is the sum of 16 and x?
The sum of 16 and x can be represented as 16 + x. This is an algebraic expression that combines the value of 16 with an unknown variable x. In order to find the sum, you would need to know the specific value of x. Without knowing the value of x, the sum remains as 16 + x.
How do you find the x-intercept from a table?
You look for the value of 0 in the y column, and find out what x has to be for y=0. This value of x is you x-axis intercept. (Reverse "x" and "y" in the above description to find the y-intercept, if there is one).
How do you find the y-intercept of -7y plus x - 1 equals 5x plus 15?
Remember, the y-intercept is where the x-value is equal to zero. The easiest way to do this is to solve an equation in terms of x, for y. -7y + x - 1 = 5x + 15 -7y = 5x - x + 15 + 1 -7y = 4x + 16 y = (-4/7)x - 16/7 Now that you have solved an equation for y, simply substitute 0 in for x to find the y-intercept. y = (-4/7)(0) - 16/7 y = 0 - 16/7 y = -16/7 This is the y-coordinate of where your y-intercept will occur. Since it is a y-intercept, the x-value is 0, giving you the ordered pair ( 0 , -16/7 ).
If 6x - 2 equals 16 what is the value of x - 3?
6x - 2 = 16 : 6x = 16 + 2 = 18 : x = 18÷ 6 = 3 :x - 3 = 3 - 3 = 0 : x - 3 = 0
What is the value of x in hexadecimal?
The value of x in hexadecimal is a numerical system that uses 16 symbols, 0-9 and A-F, to represent numbers.
10010011 base 2 to decimal?
In binary, each place value column is twice the value of the one on its right. Thus 10010011 {in base 2} = 1 x 128 + 0 x 64 + 0 x 32 + 1 x 16 + 0 x 8 + 0 x 4 + 1 x 2 + 1 x 1 = 128 + 16 + 2 + 1 = 147

Why does the binary number 10110 have the decimal value 22?
The binary number 10110 represents (1 x 16) + (0 x 8) + (1 x 4) + (1 x 2) + (0 x 1) and 16 + 4 + 2 = 22.
What is the measure of the side of 16 sq cm?
A rectangle with sides of length x cm and 16/x cm will have an area of 16 sq cm for any value x that is greater than 0.
